摘要
在新意法中,利用掌子面的稳定情况来判断隧道是否需要采取超前加固措施。文中依据摩尔库伦准则,对隧道开挖后掌子面的弹塑性状态进行研究,得出掌子面处于弹性状态的隧道最大埋深,并通过数值模拟,对得到的结果进行了验证。
In ADECO-RS Approach,whether to take advance reinforcement measure is judged by heading stability.This paper studies the elastic plasticity of tunnel heading after excavation according to Mohr-Coulomb Criterion,and obtains the maximum burial depth of tunnel with heading under elastic state.Through numerical simulation,the result is verified.
